This study aimed to analyze the volatile compounds released from the nuts of Castanopsis hystrix Hook. & Thomson., Cs. orthacantha Franch., Cs. sclerophylla (Lindl.) Schott., Cs. fargesii Franch. and Castanea mollissima Blume. Hexane nut extracts were analyzed by GC-MS and 120 compounds were identified. These included esters, monoterpenes, oxygenated monoterpenes, hydrocarbons, alcohols, aldehydes, ketones, acids, phenylpropanoids and other derivatives. Esters constituted more than half of the nut volatiles. A clustering analysis indicated that volatiles of C. mollissima nuts differed from Castanopsis spp. For instance, 6-Penty-2H-pyran-2-one and 8,11-Octadecadienoic acid methyl ester are abundant in C. mollissima, but not detected in Castanopsis. Our results indicated that rodent preference is driven by the dominance of some volatiles which gave unique nut odour of C. mollissima.
